本文对对称多步法作了一些注解,通过具体的数值计算,给出了对称多步法的局限性及它的适用范围。
This paper is a note on symmetric multistep method. By some practical numerical computations, the applicable extent and boundedness of the method are given. Symmetric multistep method maintains some characteristics of symplectic integrators for the differential equation of the type x ' (t)= f(t, x), but it is not efficient for the equation of the type x' (t) = f(t, x, x' ).
